Star Porphyrazines, Solitaire Phthalocyanines and Related Multimetallic Macrocycles

9408561霍夫曼西北大学博士布赖恩M。霍夫曼，化学系，西北大学，是由无机，生物无机和有机化学计划的化学部的支持，与安东尼G。M. Barrett，英国伦敦帝国理工学院化学系，用于合成和研究星星卟啉、单酞菁和相关的多金属大环化合物。本文合成了一系列带有不同配位环取代基的四氮杂卟啉化合物。这些将被转化为多金属阵列，金属结合到外围杂原子以及中央大环的核心。由于大环π-体系的电子离域和金属-金属相互作用，所得到的配合物可能表现出不寻常的光谱、磁性或电学性质。 含有多种金属的化合物通常具有独特的磁性和电子性质。在这个项目中，将编写一系列这类材料。具体的设计涉及一个中心金属，它被其他原子的刚性结构（大环配体）包围，其他金属连接到该结构上。这导致金属原子的星星形或线性阵列，其预期在材料研究、催化以及诊断和治疗医学等领域具有多种应用。

9408561 Hoffman Northwestern University Dr. Brian M. Hoffman, Chemistry Department, Northwestern University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for a collaborative project with Dr. Anthony G. M. Barrett, Chemistry Department, Imperial College of Science and Technology, London, England, for the synthesis and study of star porphyrazines, solitaire phthalocyanines and related multimetallic macrocycles. A series of porphyrazines bearing a variety of ligating ring subsituents will be synthesized. These will be converted into multimetallic arrays, with metals bound to the peripheral heteroatoms as well as to the core of the central macrocycle. The resultant complexes may exhibit unusual spectroscopic, magnetic, or electrical properties properties due to electron delocalization and metal-metal interactions via the macrocycle pi-system. Compounds in which contain several metals often have unique magnetic and electronic properties. In this project a series of such materials will be prepared. The specific design involves a central metal which is surrounded by a rigid structure of other atoms (a macrocyclic ligand) to which additional metal are attached. This results in star shaped or linear arrays of metal atoms which are expected to have a diversity of applications in such areas as materials research, catalysis, and diagnostic and therapeutic medicine.
